LinearFVConvectiveHeatTransferBC

Description

This boundary condition describes correlation-based convective heat transfer between solid and fluid domains. The heat flux from the fluid's perspective can be described as:

where is the user supplied heat transfer coefficient. The variables can be supplied though "T_fluid" and "T_solid" parameters. This object will automatically detect which variable matches the object's and acts accordingly. To account for the heat flux on both sides of the interface, the boundary condition should be used by both variables as shown in:
